Oh, Dusk Mane has Palkia's cry too. Okay then. I figured they used it for Dawn Wings because it sounded like a more intense version of Lunala's shriek-like cry, but it sounds nothing like Solgaleo's roar. I guess they just wanted to use Palkia's cry for no real reason then.
Anyways, another good episode. Once again, it maybe could have used a little more action, but the story was good this time, at least. I hope they eventually show us a more in-depth Legendary battle, because what they've shown so far has been somewhat disappointing. It figures that Necrozma is doing this for the good of the world. I was very surprised in the beginning to see an arc that seemed to have a Pokémon villain with no human interaction. Not upset that things turned out like this, it just makes them a little more typical.
So, this world has no light and is home to both Poipole and Necrozma, does that make it the world where the Ultra Megalopolis is located? Kind of sad they didn't bring the Ultra Recon Squad into this arc, I would have been very interested to see them animated and voiced.
Help me figure something out though. Isn't Z-Power gathered from the surrounding area? So, in this world where the light has vanished altogether, wouldn't there be no Z-Power to give Necrozma in the first place? I'm excited to see Ultra Necrozma, but this seems to be forcing things just a little.
